HENRY LAWTON NORTON, OF WATERBURY, CONNECTICUT.

SASH-FASTENER.

Application filed February 19, 1915.

T0 czZZ whom it may concern Be it known that I, HENRY LAWTON Non- TON, a citizen of the United States, residing at Waterbury, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in Sash-Fasteners; and I do hereby declare the following, when taken in connection with. the accompanying drawings and the characters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this application, and represent, in

Figure 1 a side view of a sash fastener constructed in accordance with my invention and shown as applied to the top of the lower sash of a window, and to lock that sash with the casing. Fig. 2 a rear view of the same. Fig. 3 a side view with the top of the casing removed. Fig. 4 a front view partially in section. Fig. 5 a sectional view on the line ab of Fig. 3 showing the slide in the retired position. Fig. 6 a similar view showing the slide in the open position. Fig. 7 a sectional view on the line 0d of Fig. 3.

This invention relates to an improvement in sash fasteners particularly adapted for fastening sashes of windows in a closed or partly closed position, and is an improvement on the sash fastener shown and described in Letters Patent of the United States No. 688,003 granted to me December 3, 1901.

The object of this invention is to provide a sash fastener having a locking lever and a slide which must be given two motions before the locking lever can be released, and the invention consists in the details of construction and arrangement of parts as will. be hereinafter described and particularly recited in the claims.

. In carrying out my invention, I preferably employ a case 2 and a cap 3. These parts are suitably riveted together and adapted to be secured to a sash in any desired manner. As in my previous patent I employ a locking lever l mounted upon a pivot 5 which pivot it will be noted, does not eX- tend through the case and cap, but is seated in recesses formed for it in the adjacent faces of the case and cap as shown in Fig. 41. of the drawings. This locking lever has a nose 6 which is adapted to engage with sockets 7 located in the side of a window casing or in the side of the upper sash. The

Specification of Letters Patent.

Serial No. 9,250.

locking lever is also provided with a fingerpiece 8 and with a tail Qadapted to rest upon a shoulder 10 formed on the upper edge of a slide 11, the lever being normally forced forward by a spring 12 and the edge of the lever against which the spring bears is preferably formed with a beveled edge 13 as shown in Fig. 7 of the drawings, which assists in holding the spring in place when the parts are assembled. The slide is normally retired by a spring 1 1 bearing against a head 15 formed at the inner end of a slide and against abutments 16 formed in the case and cap. This slide is formed on one side with an outwardly projecting Vshaped finger-piece 17 which bears against an inclined surface 18 formed in the cap. On the inner face of the slide is a lug 19 which is adapted to strike an inclined abutment 20 in the case, this abutment being slightly beveled so that after the slide has been drawn rearward so that the lug strikes the abutment, the slide may be moved transversely, permitting the lug to ride up the abutment until the shoulder 10 strikes the edge of the case at which time the shoulder has moved so far rearward as to allow the locking lever to swing downward and the nose 6 withdrawn into the case, thus allowing the sash to be moved. The inner end of the slide is made narrow to permit the necessary transverse movement. Upon re lease of the slide it moves inward under the action of the spring 14, and when the nose of the locking lever comes in line with a socket the locking lever will spring forward, and allow the slide to move inward bringing the shoulder 10 beneath the tail 9 of the lever and so as to again hold the lever in the locked position with its rear end flush with the case. By having a V-shaped finger piece on the slide it is impossible to move the slide rearward by the insertion of any instrument as it requires the use of two fingers to move the slide to the unlocked position; that is, it must be drawn slightly rearward until the edge can be gripped by another finger and then moved slightly sidewise before it can be brought to the unlocked position. It will be noted that whether in the locked or unlocked position, the lug 19 practically closes the opening in the case through which the finger-piece projects.

I claim 1. In a sash fastener, the combination with a case, of a locking lever pivotally provided with a nose projecting forward through the front of the case and with a downwardly and rearwardly extending tail a longitudinally I novabl'e slide inolint'ed Copies of this patent may be obtained. for

, the case below said lever, said slide formed with a shoulder upon which the tail of the lever is adapted to rest, saidslide formed with a V-shaped finger-piece projecting from one side of the slide, a lug on the opposite side of the slide, and an abutment in the case against which the lug will strike as the slide is moved rearward.

In testimony whereof I have signed this specification in the presence of two subscribng itnesses,
